The LCD/LED does that turn on Ok ?

Not an after market one but like most even Luishi they are only OEM supplied ususally. The controller is made by Nanjing Yuanlang electronic. In the case of needing to change the electronics then you will likely only need to swap out controller and lcd if used, motor wheel should/will work...

In Uk 14s battery yes, throttle no . Either way not worried at all, would do what everyone else does just call it 48v :rolleyes:.

No fees should arrive via RM or PF. My last order a BMS took only 6 days.

Aliexp using PSWPower store about £8 cheaper then Yose is you want it cheaper. The reason Iike this one is it comes with a julet/jst adapter lead, ideal for std controller use...

I have just ordered a thumb throttle I found on Aliexp a little bit different to the wuxing offerings and the main feature is ' providing steady and sensitive control of speed', so sounds like it should be a graduated one which will be nice. A bit wider at 43mm...

Any KT lcd with julet connector will work. Any pedelecer living in near to you may be able to help if they have a KT lcd , as it only involves plugging in to see if yours is faulty. Doesn't have to be lcd 3, a 1 or 2 will also work.

The shock may have affected the display internally/damaged components inside. Another remote possibility is a wire may be damaged, diagnosing julet sealed cabling is more time consuming and pin outs need to be identified. You can check the PAS fitting, KT V12L may not be seated correctly or...

The front BPM can be a bit of handful if you use a configured throttle from rest, under PAS it is not to bad if you use the PAS levels. I found mostly PAS 2 was plenty but for me though if someone had an issue then start in PAS 1 before toggling to PAS 2 OR 3 .

Code 13 bpm has lower rpm and better low speed torque, not many geared hubs as powerful as this at 250/350w. You have to also weigh up front vs rear drive, I have bpm (13) and a cst 270 rpm. The rear CST is a better ride feel, the front bpm can catch you out sometimes with it's raw power.

My Arduino is through hole not SMD so replacement is easier. Need to dig it out of the garage again to see if I will have a play with it, most likely will as the Arduino isn't very expensive and seen one that matches the criteria for < £10. Then just a case of contacting Lee again for the...

I use 37 -40c tyres on 19mm rims with my Boardman 700c .

Though not torque control as in a drive, the PAS using the 5 assist levels do give differing amp delivery levels and this is what is referred to as torque control.

Having looked up the meaning for your acronyms IC &SMD, I can now make sense of what you say. The software/ firmware is easy bit as Lee who makes/develops them will send me the necessary file/files to upload to the Arduino.

I have had hollowtech BB on five bikes and no issue with fitting a modded Mag ring you just need to think how you fix the mag ring in place.

36v will be ok if you have the right hub like a BPM @20a. Woosh Big Bear low step through, a low mileage used one currently on their website for <£900. http://wooshbikes.co.uk/?secondhand The bike kit on the one you listed is good it is a DAS KIT 48v@15a, only issue is you can't get the...

Not so....

Throttle and PAS work independently of each other so one should work if other isn't fitted. Your throttle issue isn't because PAS sensor not fitted but because P4 parameter is set for use only after pedal rotation so is value 1, if you want independent throttle use set P4 to value 0. You should...

Conversing to Lee in Korea it appears that I need to replace the 5v Arduino then upload the firmware from him or order an upper pcb with Arduino all configured and to solder the 6 pins in. Need to have a look at the Boss to see how easy any of this will be.
